' BATTERY CELL EXTRAGTOR 5 Fi led March 16. 192 8 Patented Nov. 19, 1929 UNITED STATES PATENT OFFICE WILLIS R. MUNSON, 015 FORT WAYNE, AND JOHN Q. SHIPLEY, F WARREN, INDIANA, ASSIGNOR-S T0 FIR-ED C. ZIEG, OF FORT WAYNE, INDIANA BATTERY-CELL (EXTRAGTOR Application, filed March 16, 1928. Serial No. 262,236.

This invention relates to improvements in battery cell extractors, and the object of the improvement is to afford an implement that may be readily applied to an electric storage battery and its cells extracted from their case without resorting to the use of heat to melt the agent with which the cells are sealed in place within their case. Ordinarily, the cells are subjected to more or less damage by excessive heat applied in the effort to release the cells from their bonding seal, and considerable labor is expended in removing the sealing agent preliminary to releasing the cells to permit their withdrawal from the case, and the present invention contemplates an appliance by which the seal that confines the cells in the case may be broken and the cells removed by the application of mechanical force without first reducing the seal 20 to a plastic state.

These, and other objects, as will appear, are accomplished by the construction illus trated o in the accompanying drawings in which,

Fig. 1 is a side elevation of an implement embodying the invention applied to a battery of ordinary type, parts being in section; and

Fig. 2 is an end elevation projected from Fig. 1.

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters.

The invention consists of a horse formed of a metal channel bar 1, disposed horizontally with its flanges 2 extending up, and supported at its ends upon corresponding standards 3 and 4 respectively to which it is secured by rivets 5-5. The standard 3 is riveted tightly to the bar 1 so as to be rigidly fixed thereto, while the other standard 4 is loosely riveted to the bar so as to permit outward and inward swinging movement of the standard. A retracting spring 6 attached at one end to the bar 1 and at its opposite end to the standard 4 tends to hold the standard in its innermost position.

Each standard has at its lower end a base or foot 7 formed of angle iron with one of its flanges extending down along the outer edge of the foot so that the horse, when positioned upon the battery case 8, each foot will rest upon the corresponding side wall 9 thereof and bear against the outer face of the wall to a more or less extent according to the action of the spring 6. The swinging movement of the standard 4 facilitates the placing of the horse upon the battery case and coinpensates for variations in the width of cases.

The bar 1 has a central opening 10 there r in, through which loosely extends a jackscrew 11 that is provided with a nut 12 threaded thereon, which nut is of such size as to be received freely between the flange 2 of the bar and as to be prevented by said flanges from turning relative to the bar. The upper end of the screw 11 has a squared head 13 upon which is mounted a removable wrench 14, there being a soclreted sleeve 15 on the wrench that fits upon said head, by which wrench the screw is turned in the nut 12.

i The lower end of the ack-screw 11 extends through a cross-head formed of a metal channel bar 16 disposed horizontally with its flanges 17 extending down, there being an opening 18 in the cross-head through which the jack-screw extends loosely. Upon the lower end of the jack-screw beneath the base I ing compression spring 24 through which the bolt 23 extends.

A nut 25 on the extending end of the bolt acts against the corresponding arm21 so that said pair of arms are adjustably moved respecting each other accordingly as the nut 25 is turned.

In utilizing the invention the hose is positioned upon. the battery case 8, as indicated in Fig 1,,"and the grapple members are an Said pair of arms are connected by plied to the corresponding terminal, posts 26 that extend upwardly from the battery cell 27 located in the case 8. Each grapple memher is positioned respectively with the corresponding post between its sharpened hooks, which hooks are impressed into the post forcibly by turning the nut 25, there being a socket 28 on the end of the wrench 14 for the purpose of manipulating the nut. The jackscrew is then raised by turning it in the nut 12 by which lifting force is applied to the battery cell so that its removal from the case is effected. By grasping the bar 1, the appliance, together with the extracted cell may be carried bodily away from the case.

That I claim is 1. An appliance for extracting battery cells from their case consisting of a horse provided with a main bar and a supporting standard at each end thereof, one of which standards is rigidly fixed to said bar and the other of which is loosely attached thereto so as to have outward and inward swinging movement relative thereto; a retracting spring connecting said bar and said loosely connected standard; a jaclescrew extending loosely through said bar provided with a threaded nut thereon that is normally held from rotation by said bar, there being upturned flanges on said bar engaging said nut so as to prevent turning of said nut relative to said bar; a crosshead through which the lower end of said jack-screw loosely extends centrally; a nut fixed on the extending lower end of said jack-screw engaging said crosshead; and a pair of grapple members, one at each end of said cross-head, each grapple member consisting of a pair of arms spaced apart, and pivotally connected to said crosshead, there being an inturned hook at the lower end of each arm, and a spring restrained clamping means connecting the arms.

2. An appliance of the class described, consisting of a horse applicable to the case of a battery upon the walls thereof; a jaclescrew extending loosely through the top of the horse and provided with a nut threaded thereon that is normally held from rotation by the horse; a cross-head through which the lower end of the jack-screw extends loosely, there being a nuton the lower end of the jack-screw to prevent its withdrawal from said cross-head; and a pair of grapple members, one at each end of said cross-head, each grapple member consisting of a pair of arms spaced apart and connected by a clamping means.

3. An appliance of the class described consistingof a horse applicable to the case of a battery upon the walls thereof; a. j ack-sc-rew extending loosely through the top of the horse and provided with a nut threaded thereon engageable by the horse so as to prevent rotation thereof; and a grappling detures.
